FLANGED BRAKE-SHOE.

Application filed November 17, 1914.

To all 107mm t may concern Ie it known that I, F1TZ W'ILLiAM SAR- onnr, a citizen of the United States, and a resident of Mahwah, in the county of Bergen and State of New Jersey, have made and invented certain new and useful Improvements in Flanged Brake-Shoes, of which the following is a specification.

My invention relates to an improvement in brake shoes, and more particularly to that kind or type thereof usually known and referred to as a flanged shoe, that is, a shoe comprising a body or tread portion adapted to Contact with the tread of the wheel, and a flange adapted to fit over and Contact with the flange of the wheel. In this type of shoe, usually made of hard metal, I have found that it sometimes happens that as the body or tread portion wears down in service, the flange of the wheel cuts into the flange of the shoe along the line where the latter joins the body, the flange subsequently breaking entirely away.

rlhe object of my invention is to overcome this defect, and to so construct the shoe that the flange will at all times be effectually tied or anchored to the body. This I accomplish by means of a rod or rods so bent as to extend along the body of the flanged ridge r:and into the end stops of the body of the shoe, and preferably about the center or attaching lug, so that no matter how the wheel may wear through and crack off the flange there will still be a connection or bond between the tread and flange of the shoe above the plane of the back thereof.

To better and more fully describe the invention, reference is had to the accompanying drawings, in which- Figure 1 is a top plan view of a shoe constructed in accordance with my invention. Fig. 2 is a view thereof in side elevation. Fig. 8 is a sectional view taken on the line 8 3 of Fig. 2. Fig. 4 is a similar view taken on the line 4 4 of Fig. 2. Fig. 5 is a detached view in perspective of the bonding rod. Fig. 6 is a top plan view of a modified form of the shoe showing the rod so bent as to reinforce the cast metal center or key lug. Fig. 7 is a sectional view thereof taken on the line 7-7 of Fig. 6. Fig. 8 is a similar view taken on the line 8-8 of Fig. 6. Fig. 9 is a detached perspective view of the rod employed in the shoe as illustrated in Figs. 6, 7 and 8. Fig. 1() is a top Specication of Letters Patent.

plan view of another modified form of shoe showing the employment of two rods, a portion of the top of the shoe being broken away to expose one of the rods. Fig. 11 is a view in side elevation of the same, a portion of the side of the shoe being broken away to expose one of the rods. Fig. 12 is a sectional view of the shoe illustrated in Fig. 11 and taken on the line 12-12 of the latter. Fig. 18 is a detached perspective view of the two rods employed in the shoe, as illustrated in Figs. 11 and 12.

vReferring to the drawings, 15 represents the top or'tread portion of a shoe, and 16 the flange, the central portion of the latter being preferably cut away. This shoe is preferably constructed with a steel back or reinforcing plate 17 and with a center or attaching lug 18 reinforced by the cast metal 19 of the body of the shoe, the lower extreme ends of the attaching lug 18 being anchored under the reinforcing back 17 as clearly illustrated in Fig. 3, the body of the shoe being constructed with the usual end stops 2O against which the ends of the brake head (not shown) fit or abut. Into the flange 16, and above the plane of the body 15, is located a rod 21, preferably bent as illustrated in Fig. 5, that is, with a central loop 22 to extend into the metal 19 which reinforces the lug 18, the ends of the rod being bent downwardly as illustrated at 28, the eX- treme ends 24 being somewhat flattened and bent at substantially right angles to the rod 21, in order to extend into the end stops 2O as illustrated in Fig. 1. lll/hen the shoe is so constructed it will be understood that the flange is effectively and securely tied, bonded or anchored to the tread or body portion 15, and also to the body metal 19 flowing around and reinforcing the lug 18, so that in case the flange be out into, or entirely through, by the flange of the wheel, all danger of the flange of the shoe becoming detached from the body thereof is overcome. By bending the rod as illustrated in Fig. 9, y the wrought metal lug 18 may be dispensed with as illustrated in Fig. 6. In this instance the rod comprises the arms 25, the free ends thereof being bent downwardly as illustrated at 26 and Hattened as illustrated at 27. The central portion of the rod is bent to comprise two parallel horizontal arms 28, these arms forming a loop 29 bent downwardly at substantially right angles to the arms and 28, so that when this rod is molded into the shoe the arms 25 extend through the flange at the upper portion thereof, the arms 28 into the cast metal lug 3l of the shoe, and the ends 27 into the end stops 32, the arms 2S and loop 29l reinforcing the lug 31 in such a way that the strap or wrought metal lug may be dispensed with. Again, instead of using a single continuous rod, as above described, it may be divided into two portions or elements as illustrated in F ig. 13, these rods being so bent that the arms 33 will extend through the flange 34 of the shoe, F ig. l0, the arms 35 through the end stops 36 of the shoe, the arms 37 through the body 38 yof. the shoe, and the arms 39 through the cast metal lug 40. In eachvand all of these instances it will be noted that the bonding rod is located in a plane above the back of the shoe, that is, is located in theflange and in the end stops and lug, thus permitting the shoe to be worn away in service without danger of cutting into the rod, it being essential, of course, that this rod be kept intact and out of the danger Zone of wear or injury by the tread or flange of the wheel with which the shoe comes in contact. I am aware of the fact that wires and rods have heretofore Copies ofkthis patent may be obtained for ve cents each, by addressing the been utilized lin the construction of brake shoes, and hence I make no broad claim to such, but r I/Vhat I claim is l. A brake shoe comprising a body and flange portions, and a rod embedded insaid flange and having its ends embedded in the end stops on the body of the shoe.

2. A shoe comprising a body and a flange, said body being provided with a key lug, and a rod embedded in said flange and in the cast metal of said key lug, the ends of said FITZ WILLIAM SARGEN T.
